Women beat men when it comes to picking right shade of paint

The study found men tend to find it more difficult to make fine distinctions between colours in the middle of the visual spectrum.

Women are not wrong if they think they can better decorate a house than their husbands,and men can also boast about their computer gaming skills.

Scientists say women are better able to tell fine differences between colours,but men are better at keeping an eye on rapidly moving objects.

Professor Israel Abramov and colleagues at the City University of New York reached their conclusions after testing the sight of students and staff,all over 16,at two colleges.

They found men tended to find it more difficult to make fine distinctions between colours in the middle of the visual spectrum,such as between greeny-blues (or bluey-greens). Men and women also perceived colours slightly differently.

“Across most of the visible spectrum males require a slightly longer wavelength than do females in order to experience the same hue,” the Telegraph quoted the researchers as writing in the journal Biology of Sex Differences.

Abramov,professor of cognition,admitted they currently had “no idea” about how sex influenced colour perception,but he said it seemed “reasonable to postulate” that differences in testosterone levels were responsible.

This also appeared to be the reason,he said,for why men were better at spotting fine detail and rapidly moving objects.

Men have 25 per cent more neurons in the visual cortex of the brain than women,a change that is evident even before birth.

Prof Abramov said: “We suggest that,since these neurons are guided by the cortex during embryogenesis,that testosterone plays a major role,somehow leading to different connectivity between males and females.”

Evolutionary biologists believe differences could be the result of men and women performing different tasks for millennia,the so-called ‘hunter-gatherer hypothesis’.

The rationale is that it became advantageous for men”s vision to excel at spotting and keeping an eye on distant animals,while it was more important for women”s vision to allow them to finely discriminate forage foods at a close distance.
